Trawlers with an asymmetrical load caused by a trawl net and manoeuvre opera-
tion
Application of the parameter TRM--rudder (Trim rudder).
The parameters are adjusted in that manner that the heading control will steer the ship
with a small rudder amplification and the rudder can be trimmed additional manually (de-
pending on the specific requirement).
The part of manual rudder setting is added to the part of heading control rudder setting
and is achieved as constant rudder.
The drawback of the normal heading control is, that there will be a higher integral part of
the heading control which often interferences whilst heading changes, it means that the
heading changes are too slow.
In the TRIM Mode this integral part is switched off.
With the parameter TRM--rudder as an alternative of this integral part it is possible
to react faster if it is necessary (change of loads or manoeuvres) and the heading control
stays effective in the background.
The TRM--rudder function can be turned--off by pressing the arrow--keys simultaneously.
Turning--off the integral part of the heading control
Initial state: Heading control is used according to “Tagging a load with low speed and
less manoeuvre”.
Task: The integral part on the control function shall be turned--off.
-- Activation of the Trim Rudder with the arrow--key to 1

and back to 0

.
By this the actual integral part is turned--off and can initialize itself after a heading
change again.
Override the heading control
With the TRM--rudder function a heading deviation (Starboard or Port) from the set
heading can be forced. This can be achieved by an overriding of the heading control in
that manner that a ship can deviate from the actual set heading in a range of +/--10

if
additional change manoeuvre are necessary.
The adjusted set heading value is lasted at the display as a reference, this value is auto-
matically active after turning--off the TRIM function.
Turning--off the TRM--rudder (integral part) by pressing the
arrow keys simultaneously will lead to a uncontrolled reac-
tion of the ship (heading) therefore it could be better to set
the TRM--rudder function to zero step by step.
